联邦铁路管理局说，美国铁路在满足年度截止日期的截止日期，但要建立自动火车控制系统，但九条通勤轨道线仍处于“面临”未能达到该目标的“有风险”。
为了帮助铁路以积极的火车控制（PTC）推动，FRA还为路边信号和元素内和光纤通信系统等项目授予了2.037亿美元的赠款。
FRA’s latest quarterlyupdateon Positive Train Control installation, released on Aug. 23, indicates that, as of June 30, 15 railroads have installed 100% of the equipment needed for operating the system. Another 12 carriers have 85% to 99% of the hardware in place.
PTC授权涵盖了41条铁路。
In general, freight railroads continue to achieved more progress, reporting PTC in operation on 66% of their total route-miles, up from 37% as of June 30, 2017.
通勤线滞后，系统的行驶里程的24％，仅比全年级别的水平上升了一个百分点。
FRA报道说，实际上，九个通勤铁路仍处于失踪年度目标的风险。截至3月31日，这是该类别中大约一打的改进。
九个负责遵守PTC授权的总路线中的1.1％。
九个包括繁忙的新泽西州运输网络，截至6月30日，该网络在其317辆路线上没有运行的PTC。NJ Transit还只有26％的机车配备了PTC设备。
Nancy J. Snyder, an NJ Transit spokesperson, said via email that “PTC installation remains our highest priority.” She said the agency has “made substantial progress in the last six months,” completing 60% of the FRA milestones, up from 12%.
Snyder says NJ Transit is continuing to work to meet the FRA requirements by the end of December but adds that “we have our work cut out for us over the next four months.”
FRA管理员Ronald L. Batory在一份声明中说：“尽管我们看到大多数铁路的进展，但我们希望看到每个人都满足他们的要求。”
如果铁路在12月31日之前不能遵守FRA要求，则如果他们符合六个条件，他们可能有资格获得延期或“替代时间表”。一个条件是安装了所有PTC硬件。
无论如何，扩展名不能超过2020年12月31日。
PTC是路边和元素内设备的组合，旨在防止出轨和过高的火车速度。国家运输安全委员会多年来一直建议铁路安装系统以避免事故。
FRA’s $203.7 million in PTC grants, also announced on Aug. 23, are divided among 28 projects in 15 states.
最大的赠款是向新墨西哥州的里约大都会地区运输区（处于危险的铁路之一）授予2,940万美元的奖励，以帮助在贝伦和圣达菲之间96英里处完全实施PTC。
其他大笔赠款包括伊利诺伊州的Metra系统最多2300万美元，用于岩石岛和西南服务线的光纤系统；并向马萨诸塞州湾运输局提供了多达2000万美元，以帮助完成速度执法系统的实施以及系统测试。
FRA还表示，它将在“未来几天”发布通知，以寻求另外4600万美元的PTC赠款申请。
Correction: On 8/24/18 FRA issued a correction, saying that nine at-risk railroads account for about 1.1% of total route-miles subject to PTC requirements, not 11% as it had said in an earlier press release. ENR's story reflects the correction.
